The roadshow travels with a team of internationally recognized experts, in the field of energy planning and design to help develop a sustainable agenda for cities and their neighbourhoods. The overall aim of the roadshow team is to work closely with people from the hosting city, whether they be city leaders, energy planners, local architect, professionals, academics, students and citizens. The Roadshow normally spends 3 days in each hosting city to deliver energy and urban design fun-shops in which all local stakeholders are welcome and encouraged to join and to take ownership of the final outcomes, outcomes that will allow the cities resources, both people and energy, to be directed effectively, by highlighting the energy challenges and potentials to be found in their neighbourhoods, and to finally present a sustainable ‘City Vision’.

After being postponed twice due to the measures taken as a result of the COVID-19 pandemic, the energy transition roadshow in Elburg (then immediately after in Zutphen) could continue at the beginning of September. The start took place in Elburg on 1 September. A group of interested parties, participants, civil servants and administrators was present in Restaurant De Haas (which restarted after its closure in 2020). It was the home base for three days of workshops in Elburg. From the 7 September in Zutphen, the work was carried out from Hotel Broedrenklooster. We always spoke to those involved on the basis of different themes to exchange ideas and to launch ideas. Every evening the results of that day were combined, plans were made that were further discussed and worked out the next day. Ten students from the SWAT studio were also involved in each city. Under the leadership of Professor Craig Martin (TU Delft), there was an atmosphere of working together, venting ideas and testing solutions. Also under the roadshow leadership of Craig Martin the specialized teachers Michiel Fremouw, Siebe Broersma and Leo Gommans collected, calculated and processed the first intermediate results in a total plan. Professor Greg Keeffe (Queens Universitty, Belfast) worked with student facilitators to visualize concrete design proposals and Professor Riccardo Puselli (University of Florence) translated all the data into a model in which the CO2 production of the municipalities was translated into areas of forest that should be compensated. Professor Andy van de Dobbelsteen (TU Delft) calculated which possibilities would be realistic at both locations to meet the energy demand in the future in a sustainable way.

The roadmap for the energy transition of Elburg was presented on 3 September in the Kloostertuin. A few notable parts of it are:

- For Elburg, 313 km2 of CO2 production equivalent to forest must be compensated, which is 5 times the area of ​​the municipality [AFB 8.13].
- Mobility and accessibility is a concern. The car is very present. The water can be used for public transport by boat (instead of the train). The car park offers opportunities for more activities to sell and offer local products.
- Surface water can be used for heat exchange and energy generation.
- It makes the most sense for the city center to install a heat network based on a high-temperature heat network [AFB 8.14]. The situation is different for surrounding neighbourhoods.
- The former harbor can also handle more activities, so that young people can also find their activities in the city. Food production can also be stimulated in the Randmeer [AFB 8.15].
- If all proposed solutions are implemented, CO2 production can be reduced to almost zero.
If we see Elburg, and in particular De Vesting, as a closed jar with well-preserved gherkins, it could open itself up to burst with new ideas like a test tube.

There are other opportunities and possibilities in Zutphen:
- For Zutphen, 313 km2 of CO2 production equivalent to forest must be compensated, which is 5 times the area of ​​the municipality [AFB 8.16].
- It makes the most sense for the city center to install a heat network based on a high-temperature heat network. The residual heat from industry is used and the temperature decreases via a cascade to the peripheral areas [AFB 8.17 and 18].
- The production of hydrogen is necessary to provide the industry with sufficient energy.
- The IJssel can produce energy through the flow via turbines [AFB 8.19].
- There is a lot of emptiness between the different residential areas of Zutphen. This could be activated, creating an attractive living environment for all age groups.
- If all proposed solutions are implemented, CO2 production can be reduced to almost zero.
In Zutphen, efforts are already being made to produce hydrogen, but the way in which this can be used should not go to the city center, but to industry. So that requires a different approach.

There are two challenging aspects for these two Gelderland cities. The challenge within the KaDEr project was to include the historic city center in particular in the roadmap for the municipality. What is now necessary is that the board organizes that involvement at all levels of the city, that the energy conversation continues, and that a coherent plan and planning is made for each municipality. For Elburg and Zutphen, a flying start has been made with the roadshows. They can serve as an example for all municipalities in The Gelderland.
